HOiSTlNG- `SPECIFICATION forming part of Letters Patent No. 387,657,dated August 1-, 1888.

Application filed Api-i120, ISFS.

To all whom, it may concern:

Be it known that we, NAPOLEON BRADFORD BONYPART LONG and PERRY ALFUEDAfron- LEY, citizens of the United States, residing at Prairie City,Cherokee Nation, and Indian Territory, have invented a new and usefulImprovement in Hoisting-Machines, of which the following is aspecification.

The invention relates to improvements in IOhoisting-maehines,theobjectbeingtoliftheavy weights without jar ordanger of the shaft or drum slipping backward; andv it consists in theconstruction and novel combination of parts hereinafter described,illustrated in the accompanying drawings, and pointed out in theappended claims.

Figure l of the drawings represents a perspective view of ahoisting-machine embracing the invention. Fig. 2 represents a side View2o of the machine, showing the ratchet and pawl. Fig. 3 represents adetail sectional view through the handle and correspondingratchet-wheel. Fig. 4 represents a detail view of the bed plates orblocks of the machine attached to the edge of the platform of any kind,such as the bed of a-wagon. Fig. 5 represents a plan view of the innersurface of either bed-block, theinner surfaces of which are of similarconstruction.

Referring to the drawings by letter, A and B 3o designate, respectively,the upper and lower baseblocks of the machine, of rectangular shape; anda is a bolt depending centrally from the block A and passing through acentral opening in the block B.

d is a nut that engages the bolt below the block B. The inner surfacesof the said blocks are provided with facing-corrugations d', by means ofwhich the edge of the bed of a wagon or other platform may be heldfirmly between 4o the blocks when the nntd is turned up against theblock B.

C C are standards rising from the opposite ends of the block A, and c isa bar depending centrally from the lower edge of the standard C andpassing through registering openings in the blocks A and B. The bar cserves to steady the blocks on each other.

D is a shaft journaled in bearings in said standards.

5o E is a ratchet-wheel secured on one end of Serial No. 271,277. (Nomodel.)

the shaft D, extended outside of the bearing on the corresponding side;and F is a pawl pivoted on the standard and engaging the ratchetwheeland forced into engagement therewith by a suitable spring, f, secured tothe adjacent standard.

G is a collar having a rounded outer face, which collar is fixed on theshaft D just outside the bearing on the standard opposite that adjacentto the ratchet-wheel E.

H. is a ratchet-wheel on the shaft D, to the outer side of said collar,and having its teeth inclined in the same direction as the ratchetwheelE.

I is a bifurcated lever, having the similar arms, t' i, situated on eachside of the ratchetwheel H, and provided in said arms with the slots 'i'i', through which passes the shaft D, the lever turning on said shaft.The lever I is provided with the arln t2, that stands outward at 7oright angles from its end and where the arms t' meet, and facing theradial shoulders of the teeth with the shoulders i3, that can be pushedbetween said teeth and will act as a detent or pawl to turn the shaft D,with the aid of the ratchet-wheel H and lever I. The ratchetwheel H isusually keyed or splined on the shaft D by a key as long as said wheelis wide; but if it is desired to use the lever I as an ordinarycrank-handle the said short key is re- 8O placed by a detachable key,t", long enough to project into the slot i. This key will impinge on thesides of the slots t" and enable the lever to turn the shaftcontinuously. The key is used, however, only when liftinglight weights.

J is a rope attached at one end to the shaft D, and having a hook, j, orother connecting device at its other end for the attachment of thedesired height. After the lever I has been slipped in such manner on theshaft D as to 9o engage the shoulder i3 between the teeth of theratchet-wheel H, the lever is moved in the proper direction to wind therope .I upon said shaft. The shoulder t* is then pulled away from theteeth of wheel H and turned back to its rst position ,the engagement ofpawl F and ratchet-wheel E preventing the shaft D from turning in thereverse direction. The weight may thus be lifted continuously withoutjar.

The rounded surface of the collar G prevents Ico the1 friction ofthelever I on the adjacent stand ar We do not desire to limit ourselves tothe exact manner of attaching the rope to the device or to the weight tobe hoisted; neither do we desire to limit ourselves to the mere purposeof lifting Weights, as the machine may be used in all the variousoperations in which ropes are made taut and wires stretched.

Having described our invention, we claim- I. In a hoisting-machine, thecombination of the shaft jonrnaled in the standards rising from oppositeends of the baseblock, a ratchet- Wheel fixed thereon, and the lever I,provided with the arms i t, the longitudinal slots fi '13', throughwhich the said shaft passes, and the shoulder i at the junction of thearms and facing the teeth of the ratchetwheel, substantiaily asspecified.

2. In a hoisting-machine, the combination of the shaft D, journaled inthe arms rising from opposite ends of the baseblock, the ratchetlwheel Eon one end thereof, the springeontrolled pawl engaging said Wheel, theratchet-whecl H on the opposite end of the shaft l) and turning in thesame direction as the wheel E, and the lever11andleI, provided with thearms i, slots 'i' i', arm ffl, and shonlder i, to engage the teeth ofthe ratchet-wheel H, substantially as specified.

3. In a hoisting-machine, the combination of the block A, pivoted on theblock B bythe bolt a and nut d, the standards C C, rising from saidblock A, the shaft D, the ratchetwheels E and H, the spring-controlledpawl F, engaging the wheel E, the rope J, attached tothe shaft D andhaving the hook j on its free end, and the lever-handle I, having thearms i, the slots i', the arms i2, and shoulder i, substantially asspecified.

4. InnJ hoisting-machine, the combination, with the basebloeks, thestandards, the shaft D, the ratchet-wheel E, and spring-controlled pawlF, of the ratchet-wheel H, the lever I, provided with the arms 'i andslots i', and the removable key or spline i, holding the ratchetwheel Hin place on the shaft D, and eXtending on each side of the said wheelinto the slots i7', substantially as and for the purpose specified.

In testimony that we claim the foregoing as our own We have heretoaffixed our signatures in presence of two witnesses.
